To all whom it con/cm:

Be it known thatLCnrARnns Gr. lEiuosoN,

of the city of Toronto,- in the county of York, .Province of- Untario, Canada, a subject of the Kingof Great Britain, have invented certain new and useful llmprovements in Rail Anchors, of which the TOHOW'? =emp'loy a steel having-fa fair measure of v ing is a specification.

This invention relates to rail anchors of the type shown and described in my prior United States Patent No. 1,402,852, dated Jan. th, 1922, in which there is employed a relative movement of the yoke and all) a jaw member adapted to embrace one edge of a rail base and having its back formed as a wedge, and a yoke member havin a hook at one endadapted to engage one e ge of a rail base and a hook at the other end the direction of the rail base, which causes the inclined surfaces referred to to ride on one another transversely of the rail base so that the hookspreads. slightly, and thus a marked spring pressure is exerted between the contacting surfaces tending to prevent jaw longitudinally of the rail base.

In the present invention my object is to devise a form of yoke member which may be cut out and shaped in. a die press, and which ,will possess increased longitudinal resiliency over and above the yoke member shown in the hereinbefore mentioned patent,

thus increasing the possible ran e, of the relative movement of the yoke, jaw member transverse of the rail and the consequent spring pressure between the contacting surfaces of these parts.

I attain my object by means of the construction hereinafter described and illustrated in the accompanying drawings, in which-- rail anchor inposition on the base of a rail.

Fig. 4 a plan view of a modification of the yoke member.

lln the drawings like numerals of reference indicate corresponding parts .in the different figures. -1 is a wedge-shaped jaw member adapted to fit over one edge of the rail base. While this jaw member might directly engage a liook "and,

tie..; 3 is a yoke member formed of suitable "resilient material. While it is not essential that what is known as spring steel be cmployed for "this member, it is necessary to resiliency. Thisyoke member is provided witha hook a at one end adapted to engage one edge of a rail base, while the other end In the present invention this yoke meme her is cutand formed in a die press from anoblong piece oi -steel plate intermediate ofxits ends. The yoke member, as it will. be seen particularly on reference to Fig. 3, is laterally bent or bowed. This bow ma extend towards-either side, or a compoun curvature might beemployed as shown in Fig. 4:. The result of this construction is that the yoke member is given a certain amount of longitudinal resiliency, that is to say, forces applied to the hooked ends in opposite directions tend to flatten the bowed portion of the yoke member and to spread the hooks apart,and as the metal of the yoke member is resilient, spring pressure is exerted by the hooks against any parts with which they may be engaged. ltis preferred that the yoke member adjacent the book a should lie close against the under side of the rail base, thence curving downwardly to pass under the lower part of the jaw mem ber. lit is preferred that the hooked ends of the yoke member shall extend in substantial alinement with one another as.

jaw member is fitted between the rail base and the hook 5 and the yoke is driven into position, the hook a is tightened against one Fig. 1 is a side elevation of my improved hook 5 transversely of the rail base in one direction, whilethere is more or less movea considerable part of its length, thence inment of the jaw transversely of the rail base clining downwardly and then parallel to the in the opposite direction. This causes the rail base to pass under the jaw member, the inclined surfaces referred to to ride on one engaging surfaces of the jaw member and another transversely of the rail base so that the upper part of said hook sloping inwardly the parts of the hook spread slightly and and downwardly in the direction of the between the contacting surfaces. Owing to thus a marked spring pressure is exerted rail base. i

4. A rail anchor comprlsmg a jaw member the longitudinal resiliency of the yoke memadapted to embrace one edge of a rail base her, which results from its peculiar construction, considerable movement is possible between the parts and the pressure exerted is considerably greater'than is possible with the earlier construction. It will the engagement'does not add to the effect of any component of the force exerted by engagement of the wedge.

a hook embracing the jaw member and overhanging the rail base, the said yoke member being formed of a metal plate cut to shape and having the part intermediate of its ends laterally bent to give said member longitudinal resiliency.
